Specification of Letters Patent.

Application filed March 9, 1916. Serial No. 83,037.

To all whom t may concern.'

Be it known that I, Anrroxsn ARTHUR Plomo, a nativeof Canada, and -.aresident of the borough of Manhattan, city, county,

and State of New York, have invented cerf tain new and usefulImprovements in Tooth- Brushes, of which the following is aspecification.

The object ot my invention is to afford a cheap but eiiicient sanitarytooth brush or cleaner that may be used once. and discarded to bereplaced by another,-this detachable and discardable brush pad or rubberbeing made preferably of relatively soft absorbent material so that itmay be charged with a suitable. dentifrice, antiseptic, or otherconsttuent for direct application tothe teeth and gums ot' the user.

The invention consists in the specific construction and arrangement of.parts described and claimed herein, a distinctive feature being theholder formed with a medial supporting member for the brush pad,inconjunction with elastic resilient lateral jaw members and means torclamping them medial supportin more fully set fort 1.

In the accompanying drawings,

member, as hereinafter Figure l is a ers ective View ot a tooth e i l)brush embodying the essential features of my invention;I

Fig. 2, is a central longitudinal section of the construction shown inFig. 1;

Fig. lar-ged scale taken upon plane of line SSAT-3, Fig. 2;`

Fig. 4, is a' central longitudinal sectional elevation of a slightlymodified structure;

Fig. 5, is a transverse sectionnpon an en-- l: rged scale taken uponplane of line 5 5, Fig. 4; K

Fig. (i, is a perspective view of the brush pad shown in Figs. 1, 2, and3, detached;

Fig. 7, is a similar View of the brush pad shown in Figs. 4, and 5; i

Fig. 8, is a. cross section of a brush pad in which bristles are used.

The essential features of the holder or handle H, are, the medialsupporting member k, the lateral-jawmembers 7L', 71,', and theclasp C,by means of which these members, particularly the jaw members 7L', 7L',may he clamped against the sides of the brush pad or element B, to holdit in posi- 3, is a transverse section upon an en-` tion t'or use, orreleased t0 admit of the discard ot' said brush member B.

Presuming the handle H, to be made of material having elasticresilientqualities vto a greater or less extent, as of Celluloid andsimilar compositions and materials available for the purpose, it isobvious that it' the external sides of the jaw members 71,, 7i', aretapered or inclined more or less convergently to 'ard the rear of thehandle as in Fig. 1, ot the drawings, the forward thrust of the clasp C,will force the side jaws 7M, 71.', in toward'eaeh other, therebyclamping between them the sides and base ot' the brush pad or element B,restingon the medial supporting member 71., of the handle Il.

In Figs. 1, 2, and 3, the medial tongue or support 71, is shown asadapted for insertion in a brush B, havinglate 'al extensions 71,17), tobe clamped between said medial tongue or member 71., and the side jaws71,', '71,', as shown more particularly in Fig. 3, whereas in Figs.- 4,and 5, the medial member 71, forms simply a floor support for thecomparatively solid brush pad B, the spine or base 71', of which isclamped by and between the jaws 72.', 71,", as shown more particularlyin Fig. 5. In either case the result is the same in that the brush padJor element B. is firmly secured in position on the handle Il, in Such amanner as to be available for use. If desired this result may be stillfurther insured by providing the inner sides of the jawslzf. 71.. withbarbs or protuberanccs 71,, 7L, as indicated in Fig. 5, or by serratingor lroughening said inner surfaces of the laws in a manner well known toincrease frietional contact with the brush pad B.

rlhus l do not'limit myself to any particular construction of myelongated brush pad B. as it is obvious that various modificationsthereof may be resorted to without departing tronrthe spirit and intentot my invention in this respect. For instance the base. 7)', of thebrush pad B, shown in cross l Patented Mar. 13, 1917.

application to and in the mouth of the user,

Valthough it is obvious that a powdered dentifrice, antiseptic 0rsimilar constituent may be applied to the brush pad if foiind expedient.j

In this connection it may be stated that my brush is especiallyefficacious for use in hospitals and situations where there is danger ofcontamination, infection or contagion, sin-ce it affords a convenientmedium not only for` cleanliness and sanitation, but also as a means forapplying a medicament and special treatments in the case of invalids andpatients-the brush pad being capable of immediate detachment anddestruction after use, and the handle H, being easily cleansed andsterilized by means well known.

Obviously the form of clasp C, used is of secondary importance providedits performsv the function described herein, i. c., that ofafl'ordingmeans whereby the jaws h', L, may be clamped against the brush pad Bupon the medial supporting member L, tov secure it on the handle H, inposition for use.

Nliat I claim as my invention and desire to secure by Letters Patentis,-

1. A toothbrush of the character designated, comprising a handle formedwith a. mediall supporting member and lateral jaav members of'.resilient material, a removable brush pad adapted to rest on said medialsupporting member and to be embraced by vsaid jaw members, and a claspslidabljy embracing said medial supporting member and the jaw membersfor clamping said pad in position.

2. A tooth brush of the character designated, comprising a one-piecehandle of elastic resilient material formed with a medial supportingmember and with clamping jaws extending on opposite sides thereof, aremovable brush pad supported upon said medial vsupporting member, andmeans slid- .,ably embracing said medial supporting menibervand clampingjaws to firmly clamp said pad between said jaws.
